#137 Monster S380: $49.99 Estimated Amazon $49.99 eBay
Pros: Rated for 20 hours with IPX6 water resistance, Bluetooth 6.0, aux and microSD inputs, a speakerphone microphone, TWS stereo pairing and a carry lanyard for about $50.
Cons: No measurements or substantive reviews, so its rating is estimated, and the 40 watt claim is unverified. It is made under license by Oraolo rather than Monster itself, and there is no app or EQ.
